There's some really excellent advice in this thread. If you have no opioid experience, IVing is most definitely not a good idea at all, especially something as strong as hydromorphone - could be fatal, at the very least you are likely to feel very unwell, and IV is such a dangerous and seductive ROA. As others said, it's usually something people come to after exhausting all other ROAs when their tolerance rises too high.. it carries so many risks, your tolerance will sky-rocket and it can exert a huge psychological pull over you.
In addition, IVing pills carries extra risks (in addiction to everything coered in this
IV complications megathread) - the fillers/binders can lodge in your lungs causing a permanent and progressive lung condition called pneumoconiosis (not unlike emphysema from smoking). In order to prevent this it is vital you use a
micron filter. Think of how much crap there is in a pill containing only 1mg of active ingredient..
Insufflating pills isn't ideal either, as the filler/binders can coat your nasal passages, blocking absorption of the drug and potentially causing irritation or acting as a focus for infection. Particles can also fly into your lungs and it may be possible for them to cause damage there as well. Oral is the safest method of ingestion; the bioavailability is low, but if you have no tolerance then you want that!
Definitely do not IM pills, ever! IMing can actually be considered more risky than IVing. With IV, any filler/binder/bacteria you introduce is swept away in the bloodstream, diluted down and in a position to be removed by the body's immune system should it need to be. With IM, it is all deposited into your muscle, where it sits and can develop into an abscess which can lead to sepsis, tissue destruction and even amputation. It is absolutely essential you use a micron filter, but even then it is not a good idea at all. The only thing it is safe to IM really is a sterile solution designed for IM use..
